Information technology - Generic cabling for customer premises - Part 2: Office premises
ISO/IEC 11801-2:2017(E) This document specifies generic cabling within and between the buildings of office premises, or office spaces within other types of building. Additionally those premises can include industrial spaces (for which generic cabling is specified in ISO/IEC 11801-3) or data centre spaces (for which generic cabling is specified in ISO/IEC 11801-5).
The contents of the corrigendum of April 2018 have been included in this copy.

FOREWORD
1) ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are members of
ISO or IEC participate in the development of International Standards through technical committees established
by the respective organization to deal with particular fields of technical activity. ISO and IEC technical
committees collaborate in fields of mutual interest. Other international organizations, governmental and non-
governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology,
ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
2) The formal decisions or agreements of IEC and ISO on technical matters express, as nearly
